Key activities in Step 4 include:
The step also includes assessments of the transition capabilities of the organization units involved including culture and abilitiesand assessments of the enterprise including culture and skill sets.
The resulting factors from the assessments should be documented in the Implementation Factor Assessment and Deduction matrix. For organizations where Enterprise Architecture is well established, this step can be simple, but the matrix has to be established so that it can be used as an archive and record of decisions taken.
This should include a review of the business and strategic plans, at both a corporate and line-of-business level, and a review of the Enterprise Architecture Maturity Assessment.
Review the Phase B, C, and D gap analysis results and consolidate them in a single list.
The gaps should be consolidated along with potential solutions to the gaps and dependencies. Rationalize the Consolidated Gaps, Solutions, and Dependencies matrix. Once all of the gaps have been documented, re-organize the gap list and place similar items together.
When grouping the gaps, refer to the Implementation Factor Assessment and Deduction matrix and review the implementation factors. Any additional factors should be added to the Implementation Factor Assessment and Deduction matrix.
This functional perspective leads to the satisfaction of multiple requirements through the provision of shared solutions and services. The implications of this consolidation of requirements with respect to architectural components can be significant with respect to the provision of resources.
For example, several requirements raised by several lines of business can be resolved through the provision of a shared set of Business Services and Information System Services within a work package or project.
The Architecture Vision and Target Architectures, as well as the Implementation Factor Assessment and Deduction matrix and Consolidated Gaps, Solutions, and Dependencies matrix, should be consolidated and reviewed to identify any constraints on interoperability required by the potential set of solutions.
A key outcome is to minimize interoperability conflicts, or to ensure such conflicts are addressed in the architecture. Any such conflicts must be addressed in the architecture, and conflicts must be considered across all architecture domains Business, Applications, Data, and Technology. There are two basic approaches to interoperability conflicts; either create a building block that transforms or translates between conflicting building blocks, or make a change to the specification of the conflicting building blocks.
There are several key dependencies that should be taken into account, such as dependencies on existing implementations of Business Services and Information System Services or changes to them.
Dependencies should be used for determining the sequence of implementation and identifying the co-ordination required. A study of the dependencies should group activities together, creating a basis for projects to be established. Examine the relevant projects and see whether logical increments of deliverables can be identified.
The dependencies will also help to identify when the identified increments can be delivered. Once finished, an assessment of these dependencies should be documented as part of the Architecture Roadmap and any necessary Transition Architectures.
Addressing dependencies serves as the basis for most migration planning. It is important to identify, classify, and mitigate risks associated with the transformation effort. Risks should be documented in the Consolidated Gaps, Solutions, and Dependencies matrix. There are three basic approaches as follows: The most common implementation methodologies are: Quick win snapshots Achievable targets Value chain method These approaches and the identified dependencies should become the basis for the creation of the work packages.
This activity terminates with agreement on the Implementation and Migration Strategy for the enterprise. Using the Consolidated Gaps, Solutions, and Dependencies matrix together with the Implementation Factor Assessment and Deduction matrix, logically group the various activities into work packages.
Fill in the "Solution" column in the Consolidated Gaps, Solutions, and Dependencies matrix to recommend the proposed solution mechanisms. An existing system may resolve the requirement with minor enhancements. For new development this is a good time to determine whether the work should be conducted in-house or through a contract.
Classify every current system that is under consideration as: Analyze and refine these work packages or increments with respect to their business transformation issues and the strategic implementation approach. Finally, group the work packages into portfolios and projects within a portfolio, taking into consideration the dependencies and the strategic implementation approach.
These provide an ability to identify clear targets along the roadmap to realizing the Target Architecture. The Transition Architectures should provide measurable business value. The time-span between successive Transition Architectures does not have to be of uniform duration.
Development of Transition Architectures must be based upon the preferred implementation approach, the Consolidated Gaps, Solutions, and Dependencies matrix, the listing of projects and portfolios, as well as the enterprise's capacity for creating and absorbing change.
Determine where the difficult activities are, and unless there are compelling reasons, implement them after other activities that most easily deliver missing capability.
The flexibility of AWS allows you to design your application architectures the way you like. AWS Reference Architecture Datasheets provide you with the architectural guidance you need in order to build an application that takes full advantage of the AWS cloud infrastructure. The enterprise technology architecture (ETA) viewpoint defines reusable standards, guidelines, individual parts and configurations that are technology-related (technical domains). ETA defines how these should be reused to provide infrastructure services via technical domains. To maximize application potential and user experience, EA and. In information systems, applications architecture or application architecture is one of several architecture domains that form the pillars of an enterprise architecture (EA).   An applications architecture describes the behavior of applications used in a business, focused on how they interact with each other and with users.
